LABORATORY APPARATUS Specification of Letters Patent.

Patented Oct. 23, 1919.

Application filed March 21, 1919. Serial No. 284,151.

To all whom it may concern:

Be it known that we, SAMUEL DRUCKER and WILLIAM SIECK, Jr., citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Laboratory Apparatus, of which the following is a specification.

This invention relates to improvements in laboratory apparatus especially designed for experimental purposes in treating liquids with gases under pressure or vacuum heat, and is particularly adapted, though not necessaril limited in its use for treating oils carrymg an oxidizing agent in suspension therein, with air for determining the value of the oil in varnish manufacture or for other urposes or for treating a mixture of oil and a. suitable catalyst with hydrogen for the purpose of hydrogenation experiments.

To the attainment of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty, in substantially the construction, combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawing illustrating this invention and in which- Figure 1 is a top plan view of an improved apparatus of this character constructed in accordance with the principles of this invention.

Fig. 2 is a vertical sectional view taken on line 22 Fig. 1.

Referring more particularly to the draw ing the apparatus consists primarily of a chamber or cylinder 10 of a suitable size for laboratory experimental and testing purposes and may be constructed of any suitable material capable of withstanding considerable internal and external pressure, and of any desired configuration.

The bottom of this cylinder is shaped to form a downwardly projecting conical portion 11 provided at the lowermost point 12 with a discharge outlet by means of which thecontents'of the apparatus may be completely drained. This outlet 12 is provided with a valve 13 by means of which the outlet may be controlled and the apparatus thus constructed is supported in an upright position preferably by means of legs or supports 14.

Arranged below the conical portion of the vessel is an annular burner 15 adapted to be supplied with gas-or fuel from any suitable source through the inlet opening 16. The burner is so arranged that it will stand in close proximity to and encompass a portron of the conical bottom 11 and is provlded for the purpose of heating the contents of the vessel.

A heat retaining jacket 17, constructed of any suitable material is arranged around the vessel 10 and is of a size to be spaced therefrom and may be supported in any suitable manner. The bottom of the jacket terminates above and adjacent the burner 15 so that the products of combustion from the burner will be directed into the jacket to be confined therein around the vessel 10 to assist the heating of the vessel. The jacket 17 may be provided with any desired number of outlet openings 18 to ermit the escape of the products of com ustion and to assist in causing a circulation of the heated air around the vessel.

The vessel is provided with a closure 19 of any suitable type, and this closure is held in position by means of suitable fastening devices 20. Arranged Within the vessel is an agitator 21 preferably of a fan shape and is located in proximity to the bottom 11 of the vessel. The agitator 21 is connected with a shaft 22 which passes through the closure 19 and also through a suitable stufling box 23, and the stuffing box prevents the escape of gases or ii uids under pressure which are contained within the vessel 10.

The closure 19 is provided with an opening 24 therethrough, and secured in this opening by one end is a tube or pipe 25 which latter is located within the vessel 10, and the outlet end 26 of the tube extends into the outlet opening 12 of the conical bottom 11 so as to discharge fluid into the vessel at that point. Connected also with the opening 21 is a supply pipe 27 for the purpose of conveying gases, air,- or other fluids into the tube 25 to be discharged into the vessel 10. A pressure gage 28 may be provided in this pipe 27 and a controlling valve 29 may also be provided for controlling the amount of fluid delivered to the tube 25. Supported by the closure 19 is a tube 30 which extends into the vessel 10 and is provided with a closed end 31. The upper end 32 of the tube is open and access may be had thereto through the closure 19. This tube serves as a receptacle into which a thermometer may be placed for the purpose of ascertaining the temperature of the contents of the vessel 10. i

The closure 19 is also provided with another opening 33 adapted to serve as a fill opening and seated within this opening 33 is a plug 34 which latter may be fitted with a valve or cock 35 by means of which the pressure within the vessel may be relieved. The valve 35 also serves as a means whereby the vapor or gases contained within the vessel 10 and above the liquid therein may be exhausted to create a vacuum or partial vacuum, by attaching any suitable exhaustingapparatus to the valve 35.

otary motion may be imparted to the agitator 21 in any desired or suitable manner but preferably by means of a pulley 36 connected with the shaft 22.

With this improved construction it will be manifest that there isprovided a very simple, eflicient and handy apparatus for laboratory use by means of which certain or desired experiments may be performed and in use, the liquid is placed within the vessel 10 and agitated by means of the agitator 21, and" during this agitating operation the liquid will be heated by means of the burner 15. The conical bottom of the vessel also operates to equally distribute the flame over the bottom of the vessel. ing this agitating and heating) operation, another and different fluid may e delivered to and discharged into the vessel 10 through the pipe 27 and tube 25 and this fluid is such that it will commingle with the liquid in the vessel.

By arranging the discharge outlet of the tube 25 so that it will terminate within the opening 12 of the bottom and at the lowermost point of the receptacle, all of the heavier particles of the liquid will be mamtamed in suspension as the inei'miing fluid operates also as a fluid agitator so as to maintain the particles in suspension.

Obviously many changes may be made in the form of the apparatus and in the details of construction and in the arrangement of the parts, within the scope of the claims without departing from the spirit of this invention.

What is claimed as new is 1. A laboratory experimenting or testing apparatus embodying a chamber having a downwardly extending substantially cone shaped bottom with a discharge outlet leading from the lowermost point thereof, means for controlling said outlet, a closure for the .chamber, means for introducing into the chamber the liquid to be treated; means for agitating the liquid, a heater for heating the liquid, and means for introducing another and different fluid into the chamber and discharging the same into the liquid at the Durlowermost point of the said chamberand below the agitator.
